Be it known that 1, G-EoRG-E'WHITEFIELD STAFFORD, of Postville, in the county of Allamakee, in the State ot' lowa, have invented a new and Improved Mode of MeltingwMetals and Ores of all Kinds; and I do hereby declare that the following' is a full and exact description thereof, reference being had to the accompanyingdrawing, and to the letters of reference marked thereon.

The nature of my invention consists in applying rubber hose to the upper part of a blacksmiths bellows, as shown in that part of the drawing,` marked A, which conducts the wind by the means of an iron blow-pipe (marked B) attached to hose, and held in the hand of" operator, which conducts the wind into the crucible marked C; at "the same time the bellows is keeping the re around the crucible very hot, using best stone-coal on the main re outside of Crucible, and the best charcoal in the inside of samethe charcoal to be set on re at the same time that the crucible is placed in the main re. Then the blast is to be kept up in the hose, and in the bellows-pipe leading to the'main tire, causing a powerful January 20, 1876.

heat inside and out, keeping the crucible full of charcoal until a white heat is obtained. Thenput in the metal or ore to be melted, in small quantities, and as it disappears beneath the charcoal, add more, until the required 4amount is in then skim charcoal ol'the melted nlatter, which is then ready to pour oft'. By

this process any one having` a common bellows or foundry-blast can melt brass, copper, gold, silver, iron, and all kinds of ores as easily as Babbitt metal was formerly melted by the old ladle process. Y

What I claim as my invention, and desire to secure by Letters Patent, is

The combination, with the crucible and bellows for supplying the blast to the lire beneath the crucible C, of the hose A, connected with the bellows, and provided with the blow-pipe B, for supplying the blast into the crucibleG, all arranged and operating as and for the purpose set forth.
